Specification of Letters Patent.

Patented July 19, 1916."

Application filed September 15, 1909. Serial No. 517,781.

To all whom it may concern:

' Be it known that I, SYLVESTER KozLowsKI, a citizen of th'e-UnitedStates of America, residing at Detroit, in the county of Wayne and Stateof Michigan, have invented oer-- useful Improvements in.

taln new and Keeper-Plates for Door-Locks, of which the following is a secification, reference being had therein to the accompanying drawings.

This invention relates to door locks and latches and more artioularly tothe keeper plate thereof whic is secured to the frame of the door toengage the locking bolts or latches.

The object of the invention is to provide the keeper plate with simpleand convenient means to take up any loose play due to shrinking of doorsor door casings and prevent the rattling thereof.

To this end the invention consists in an adjusting device applied to thekeeper plate so that i the knob latch should have a loose play in thekeeper this looseness may be readily taken up without interferin withthe keeper plate all as more fully heremafter described and shown in theaccompanying drawings, in which,

Figure 1 is a perspective view of the keeper plate embodying myinvention, the new showing the rear side of the plate; Fig. 2 is anelevation of the rear side of the keeper plate; and Fig. 3 is a crosssection on llne xa*, Fig. 2 showing by dotted lines its position in thedoor frame.

The device consists of the stationary keeper plate 1 provided in itsrespective ends with the screw holes 2 for the insertion of the usualscrews in securing the same to the door frame. The keeper plate has theusual slot opening 3 for the reception of the knob latch except that theopening is made a little wider 1n its horizontal dimension to affordadditional room for the inturned lip 4 formed at the front end of anadjusting late side of the lock strike of the keeper plate b means of ascrew or headed in 6" whic passes through a slot 7 in t e adjustingplate.

The adjusting plate 5 is rovided with an offset forming an ear 8 and acorresponding offset or ear 1s rovided on the front edge of the strikeoft e keeper plate and through these ears passes an adjusting screw. 10in such manner that by turning the screw, the adjusting plate 5 can bemoved in relation to the keeper plate.

As shown in Fig. 3 the inner end of the adjustingplate with the lip 4which guides the lates 1n the opening, ositions the knob therein andthus i by shrinkage or otherwise the knob latch should have a loose playtherein, it can be readily taken up by means of the adjusting screwwhich is exposed and readily accessible allowing the adjustment to bemade accurately and qulckly while the door is closed.

My device thus accomplishes the ob ect of the invention in a very simplemanner and does away with the trouble of resetting the kee er platewhich requires particular sk1ll.-

at I claim as my invention is The combination with a keeper late of adoor latch or lock having a late strike extendin out in front beyond theportion covered the edge of the door, of a plate horizonta 1y adjustablysecured to the back of said latch strike and having its rear edge formedwith a vertical off-set pro ect ng into the latch opening and formlngthe front wall of said opening. v

In testimon whereof I afiix my signature in presence 0 two witnesses.
